Intel launched the first quad-core Ivy Bridge parts last month and today it expanded its lineup with 14 dual-core mobile parts.

Of the 14, four fit into the ultrabook 17W thermal envelope, feature hyperthreading, turbo and HD 4000 graphics clocked at 350MHz to 1150MHz.

The Core i7-3667U is the fastest of the bunch, with a base CPU clock of 2GHz. It can hit 3.0GHz in dual-core turbo mode, or 3.2GHz in single-core mode. It features 4MB of L3 cache and it is priced at $346, which sounds pretty steep. The i7-3517U is a 1.9GHz part and its turbo clocks are 200MHz lower, while the rest of the spec is the same and we still don’t know its price.

The Core i5-3427U features a 1.8GHz base clock and it can hit 2.6/2.8GHz on turbo. It has 3MB of cache and the price is $225. It’s little brother, the Core i5-3317U, is a 1.7GHz part, with turbo clocks set at 2.4/2.6GHz. No word on price.

Intel’s chipset of choice for the new ultrabook Ivy range should be the UM77, with a TDP of 3W and average power consumption of just 0.84W.

After the recent leak of desktop Ivy Bridge, keen eyes of VR-Zone LG Nilsson spotted a full set of slides revealing the mobile part of Ivy Bridge lineup that should appear in May, or begining of Q2 2012 if you will. Launching together with the three mobile 7-series chipsets, the full lineup will include a total of three quad and three dual-core CPUs released under Core i5 and Core i7 series branding.

As noted, the chipset lineup, aka Chief River platform, includes three main chipset, the HM75, HM76 and the HM77. There is also a variation of the HM77, called UM77 that should target low power notebooks. The HM75 and the HM76 are pretty much identical except the lack of the USB 3.0 support on the HM75. The HM77, when compared to the other two, has RAID support and two extra USB 2.0 ports. The UM77 can be considered "a cut down to basics" version of the HM77 as it only has four SATA ports (one of the SATA 6Gbps), has four less PCI-Express lanes and only four USB 2.0 ports.

The CPU lineup starts with a top notch quad-core Core i7-3820XM, part of the Core i7 Extreme lineup. The new Core i7-3820XM is clocked at 2.9Ghz with single, dual and quad-core turbo set at 3.8, 3.7 and 3.6GHz. It pakcs 8MB of L3 cache, TDP set at 55W, and features Intel HD Graphics 4000 clocked at 650MHz with 1300MHz Turbo.

The next two Core i7 quads, the i7-3820QM and the i7-3720QM are clocked at 2.7 and 2.6GHz. The Core i7-3720QM also has 100MHz lower turbo clocks. The Core i7-3820QM also features same 8MB of L3 cache as the Extreme part but Intel's HD Graphics 4000 is clocked at 650/1250MHz, a 50MHz lower in Turbo. This one will have a 45W TDP, same as the Core i7-3720QM clocked at 2.6GHz with 6MB of L3 cache and same clocks on Intel's HD 4000 graphics.

The last of the Core i7's is the Core i7-3520M, a dual-core part clocked at 2.9GHz with 3.4GHz max Turbo, 4MB of L3 cache and a 35W TDP. The dual-core lineup continues with two Core i5 parts, the Core i5-3360M and the Core i5-3320M. Both have the same 3MB of L3 cache, 35W TDP and Intel HD Graphics 4000 IGP clocked at 650/1200MHz. The only difference is actually the base clock set at 2.8GHz for the i5-3360M and 2.6GHz for the i5-3320M.

The lineup of Ivy Bridge CPUs also include two U-Series CPUs, a dual-core 2GHz clocked Core i7-3667U and the dual-core 1.8GHz clocked Core i5-3427U. The faster one, i7-3667, will feature 3GHz max Turbo, 4MB of L3 cache and Intel HD Graphics clocked at 350/1150MHz. The slower, Core i5-3427U has a slightly lower 2.6GHz max dual-core Turbo, 3MB of L3 cache and same clocks on the Intel HD Graphics 4000 IGP. Both of the U-Series CPUs will have an identical 17W TDP.

It is important to note that the entire lineup now includes support for DDR3-1600 memory. According to the info, Intel's mobile Ivy Bridge lineup might come in May but slides do mention that quad core models might even be available in April.
